How does one connect the ground pour under a chip with the gnd pin? I've
got a sot-89 chip and I have the ground pour touching the gnd pin but when I
run the drc it gives me an error saying they are too close? Any ideas?
Thanks,
DeWayne

The polygon name has to match the net name of the ground pin. That is if
you added the polygon to the board not the lib part.

Thanks for the info. What if I want to do it in the part?

No clean way in ver 4.xx I have not upgraded to 5.x+ but from what I
gather in the discussions you can add copper to lib parts but it can't
be done without DRC errors. You can approve them.
The best no DRC error way it to put the stop mask in the lib and add the
polygon to cover that area on the board.

Hi,
I have made some DPAK library parts with ground pour defined as gnd. In
fact, ground pour is defined as a pin with name GND like any others. And
i have no DRC error. If you give me the part number and the link where
its datasheet is located, then i may make a library part and send you back.
Firat,
